Ad Hoc Mode
Ad-hoc mode is also called “peer-to-peer mode” or “Independent Basic Service
Set (IBSS).” In ad hoc mode (Figure 38), devices communicate directly with each
other without using an Access Point (AP).
An ad hoc wireless LAN consists of a group of computers, each equipped with a
wireless adapter, connected via radio signals as an independent wireless LAN.
Computers in a specific ad hoc wireless LAN must therefore be configured to the
same radio channel. An ad hoc wireless LAN can be used for a branch office
operation.
